Thin Berries

Antioxidants from blueberries may have a slimming effect, a study suggests. Researchers at Texas Woman's University treated mouse cells with either blueberry polyphenols (in three different doses) or a control solution. The active compounds blocked the growth of new fat cells and the buildup of lipids inside cells, reducing total fat by up to 73 percent at the highest dose. In theory, this cellular reaction would decrease body weight, but the implications for humans aren't yet clear, emphasizes Shiwani Moghe, who worked on the project as a graduate student. Polyphenols from green tea, grape seeds, oranges, and grapefruits have also been shown to inhibit fat cells, so Moghe recommends eating a variety of antioxidant-rich foods and supplements.
